Bay View lawyer Joe Trawitzki said he has the records to prove it, but Dimitrijevic is disputing what the records really show.

At issue is the number of card swipes -- how many times Dimitrijevic used her entry card at the gate to the secured parking lot, or a crosswalk door, over a two-month period.

"The point is, she's not working anywhere near a full-time job," Trawitzki said.

Trawitzki, who once ran against Dimitrijevic, used an open records request to find that the supervisor used her key card at the courthouse parking lot on just 16 of 48 recent work days.

The County Board is a full-time job but will become part-time in 2016, which is something Dimitrijevic fought.

"If she's treating it as a part-time job now, then what she has to do right now is give back that money that she's not earning," Trawitzki said.

He also found that County Executive Chris Abele was at the courthouse more than twice as often over the same period, and Abele told WISN 12 News he thinks the question being raised is a fair one.

"I think it's especially fair because she was elected by constituents, and her salary and that of the board staff is paid for by taxpayers," Abele said.

WISN 12 News reporter Kent Wainscott tried to ask Dimitrijevic about Trawitzki's claims. He was told that she had been in the office earlier Thursday, but wasn't available and wouldn't talk on camera, instead issuing a written statement calling the claims a baseless attack.

Trawitzki said it's about accountability.

"She's the leader of the board, she took on the added responsibility, and there's so many things happening at the courthouse, she needs to be there," Trawitzki said.

The chairwoman issued a statement saying, "This is a record for a parking lot, not work on behalf of constituents that I do everyday."

She said met with Abele two days ago and said, "County business is not just done at a desk or in the courthouse. Clearly, this is another baseless attack. This time, by a defeated opponent of mine."

This is an issue voters may soon consider because Dimitrijevic is running for the state Assembly and faces three other Democrats in a primary next month.
